how do i export multiple .fbx, with one material, and one texture map?
I think the simple way is to have all your model in one .blend, which share their unique material, and export one by one with selected only checked.



Then in Unity, you just have to set this in all your models setup :


Unity will know that material allready exist, so it will be instanciate.

Unless you work in team, so you want one .blend by models : obviously you have all to use the same naming convention for the material, and with the same option in unity import above, it will probably works.
